Alarm 14700

Siemens 14700 - Block timeout during command to interpreter

SINUMERIK alarm 14700 occurs when the NCK geometry processor detects that active tool radius compensation (G41/G42) would cause the compensated tool path to intersect with previously machined geometry or create impossible tool movements. The alarm is triggered by the internal collision detection algorithms in the geometry processor when calculating the offset tool path.

Block timeout during command to interpreter

Siemens SINUMERIK alarm 14700: Block timeout during command to interpreter. Detailed remedy is being verified against the current Siemens diagnostics manual.

Root Cause Summary

SINUMERIK alarm 14700 occurs when the NCK geometry processor detects that active tool radius compensation (G41/G42) would cause the compensated tool path to intersect with previously machined geometry or create impossible tool movements. The alarm is triggered by the internal collision detection algorithms in the geometry processor when calculating the offset tool path.

Safety

  • Only qualified personnel should diagnose and clear control alarms; follow the machine builder's safety procedures and lockout/tagout where hardware work is required.

Causes and Fixes

  1. 1

    Check Active Tool Radius

    Press OFFSET key, select tool offset table, verify D-word radius value for active tool number matches actual tool radius.

    Use SINUMERIK's tool measurement cycle to automatically set accurate radius values

  2. 2

    Analyze Part Geometry

    Review NC program for inside corners, slots, or arcs smaller than 2x tool radius. Check G02/G03 arc definitions and corner transitions.

    Sharp inside corners (G01-G01 transitions) are most problematic for radius compensation

  3. 3

    Modify Tool or Program

    Either select smaller tool radius or modify part geometry to accommodate current tool. Update D-word offset value accordingly.

    Use SINUMERIK's simulation mode to verify compensation path before execution

DIY Feasiblehigh confidence

Call a technician if:

  • ·Machine data parameters require modification
  • ·Persistent alarms after tool and program verification
  • ·Suspected NCK software corruption

Prevention

  • Always verify tool radius matches D-word offset values
  • Use adequate lead-in/lead-out distances for compensation
  • Simulate programs with compensation active before execution
  • Maintain consistent tool data in offset tables

Common Mistakes

  • Using wrong compensation direction (G41 vs G42)
  • Insufficient approach distance for compensation buildup
  • Programming features smaller than tool diameter
  • Canceling compensation during complex geometry
